IMPROVEMENT IN HEATING-STOVES.

Specication forming part of Letters Patent No. 133,132, dated November 19, 1872.

To all whom it may concern:

Be it known that I, .THOMAS WHITE, of Quincy, in the county of Adams and State of Illinois, have invented a new and useful Improvement in HeatingStoves; andI do declare that the following is a true and accurate description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon and being a part of this specication, in which- Figure l is a perspective view of an external-flue stove fitted with my improved m0va-k ble tlues 5 Fig. 2 is a detached perspective view, showing the upper part of the ii'ue and collar; and Fig. 3 is a cross-section of the stove at a: a: in Fig. 1.

Like letters refer to like parts in each gure.

The nature off this invention. relates to an improvement in the construction of that class of stoves which have external hollow columns, serving as diving and ascending iiues, connecting a double top with a double base; and

has for its object to so construct and attach the said columns that they may be readily removed for the purpose of cleaning them and `the top from soot and ashes which accumulate front corner projecting parts of the double top and base; and E Eare similar columns connect` ing the rear corners of the top and base. The heated currents descend through the columns D D into the base, which they traverse and issue from, rising through the columns E E into the back part of the top B, whence they find an exit through the Smoke-pipe F, as indicated by the arrows in Fig. 3. All the columns at' their bases slip over collars or flanges surrounding the several openings in the upper plate of the base. The front half of each flan ge about the openings in the lower plate of the top is cut away, as seen at a, Fig. l. In the top of each column is inserted a metallic collar, G, having a 11a-ring iiange, the rear half of which is cut away, as at c. This cut-away part at the top edge may have a groove in it to form a dust-joint, if desired. The column is placed on the collar of the base-openin g and pushed back to place at the top, the top having a semicircular pendent ange to receive the back edge of the collar G, Whose front or higher half shuts against the iiange of the toppate opening, and thus forms a smoke-proof joint. A button, c, pivoted to the rim of the top, may be turned over the collar G to hold it securely in place.

To clean out the .top and columns where soot and ashes chiefly accumulate in stoves of this class, turn the button c and remove the iiues, clean them and the top, and replace the iiues, which is thus done without loosening the nuts of the stove-rods or disturbing the body of the stove.

This improvement is applicable to all coal or wood burning stoves which have external dues.

I do not claim the invention of the reverted draft stove shown; but

What I do claim as new, and desire to secure by Letters Patent, is-

The detachable lue D, provided with the collar G, constructed as described, in connection with the flange a of the top plate B, as and for the purpose set forth.
